WITNESSES 4 TTOR/VEYS JOHN AUSTIN BEST, OF AUGUSTA, GEORGIA.

VISIBLE AND EXPANSIBIJE CARD-INDEX.

To all whom it may concern:

Be it known that I, J OHN AUsTIN Bns'r, a citizen of the United States, residing at Augusta, in the county of Richmond and State of Georgia, have invented certain new and useful Improveme ts in Visible and Expansible Card-Indexes, of which thefollowing is a specification.

My invention has relation to. visible and expansible card indexes.

The main object of the invention is to provide various means to enable one to expose to view or make visible names or other indicia contained on the index cards of card indexes. I

A further object of the invention is to provide means to accomplish the above without consuming any additional space than that.

"now utilized by the common types of card index systems now on the market.

A further object of the device is to provide means to carry out the above objects in a simple, expeditious, eflicient and effective manner.

A still further object of my invention is to produce a device of the character above indicated, which may be termed a self-indexing card system.

With the foregoing and other objects in view my invention consists of the novel features of construction, combination and arrangement of the several parts of my invention, which are described in this specification, illustrated in the accompanying draw ings forming a part thereof and particularly pointed out in the appended claims.

Generally speaking, my present invention relates to a card having, at one edge at least, a space, groove, channel, or the like,

to receive a portion of the same edge of an adjacent card in a series in order that by pressure upon the series of cards at the said edges, movement of the opposite edges away from one another will be caused. Thus the latter edges shifted away from one another will be placed in position where the indicia,

as for instance the names, will be simultaneously exposed to view. My present invention contemplates for the above purpose, a card having an extension along one or more edges projecting beyond the main body portion of the card, and which may be either reduced or offset with respect to the card body, although the reduced extension is to be preferred as it avoids additional parts and attachments.

Specification of Letters Patent.

In the accompanying drawings illustrating my present invention:

Figure 1 is a face view of one card embodying the invention;

Fig. 2 is an edge view thereof;

form of Fig. 3 is a face view of another form' illustrating the extension in the nature of an attached part;

Fig. 4 is an edge view of a series of cards, each constructed as in Fig. 3, placed to illustrate the practical use thereof; 7

Fig.5 is a face view of another form of the. invention; 7

Fig. 6 is an edge view of the card shown in Fig. 5 and other cards similar thereto;

Fig. 7 is a face view of still another modi- -fied form of card, and, 1

Fig. 8 is an edge view showing a series of the cards of Fig. 7 in the position illustrating their practical use.

In Figs. 1 and 2 I have shown a card 10 embodying my invention by virtue of its formation from a strip of material folded upon itself to form the main body of the card, which it will be noted from Fig. 2 is of substantially uniform thickness, the extension of the card in this case being constituted by one free edge of one fold which projects beyond the adjacent edge of the other fold, as seen at 11. It is obvious this extension 11 may be duplicated at all edges of the particular form of the invention under consideration, except the folded edge.

In Figs. 3 and 4: I have shown that the same result may be accomplished by an additional strip 12 pasted or otherwise fastened securely along at least one edge of the card 13 to project therebeyond and uniformly for the full length of the said edge, thus constituting an offset extension, enabling the desired action to take place in use as will be observed from consideration of Fig. 4.

In Fig. 5 I have shown a card 14 which, as will be observed by reference to the first card of Fig. 6, is made up of two layers 15 and 16, the bodies of which are oifset with respect to one another, so as to produce extensions 17 and 18 at the opposite edges thereof, the cards being thus reversible.

By reference to the card 19 of Fig. 6, however, it will be noted that the two layers need only be offset at one edge to produce the desired result, and by reference to the card 20 of Fig. 6 it will be noted that the body need not be in two layers, but may be made of a single ply reduced invthickness along one edge to produce extension 21.

In Figs. 7' and 8 I have shown a three ply card, the central layer.or r,ply--22;;of which is extended beyond the edges of the two side layers or plies-23 to produce extensions 24:,

the card so constructed being reversible and being capable of the desired-action-in a horiz 0ntal,,,as Well as a vertical direction.

"It-is obviousfrom a consideration of the foregoing that allof the forms illustrated and'des cribed, provide an extension along at least one edge, so placed asvto form a space ously exposed to View.

' 'I claimz 1. A ard indexcOIIsistingof a plurality lofvcards, each of Which has means along 3 oneredge thereof ltoqform a space adjacent and along said edge arranged to receive a portion-.ofs'thernext adjacent card at one side thereof, for the purpose described;
